T0 all whom tmoy/ concern y Bel it known that we, Gnouer. ERNEST MALLo'rfr, CHnIsTornIcn Jol-Insert, and JOI-IN WILLIAM Mooney, subjects oit' the King ot' `Grreat Britain, residing, respectively, at

y Moorsidef7 Ribbleton avenue, Preston. 251

Manchester" road, Preston, .and 10 Elijah street, Preston, all inLancashire, England, have Invented new and useful Improvements in Loom-Reed-.Locking Motions, ot `which I to the warp by `obstruction on the part of such shuttle, and to prevent or minimize this the reed is either mounted so as to be capable of l swinging `out or yielding to `the abnormal pressure, or means are provided to check the advance of the slay so that the full beat-up :may not taire place. The latter device entails considerable shock to the loom, while the use of a permanently loose reed limits the character ot' the fabrics produced inthe loom.` To overcome this i diflicillty,`

means have been proposed to keep the reed normally locked in positionexcept at those times when the shuttle fails toenter the box and is trapped in the shed, when thereed is released by mechanical means and becomes for the time being a loose reed. By our in vention a reed of this character is provided with a retaining clamp and clamp connections which latter are of thekind which are movable transversely of the lower part ot the loom slay, for release of `the reed, and

are combined with means whereby each` clamp connection is constantly locked in positionwhenever the loom is working prop-` erly, for retaining the reed whether the shuttle is in the shuttle box or not, and is unlocked forrelease of the reed when the shuttle stops inthe shed.

l/Vith reference to the accompanying drawings, Figure 1 is a cross sectional view,"

partly in elevation, of the slay and reed portion of a loom provided with means for holdingiastor releasing the said reed under the conditions aitoresaid, and according to one form oi our invention. i Fig-.2 is la similar view to Figl, the partsbeing, however, inthe released position. Fig. Bis I y a sectional plan view of F1 g.` l, a few details being omitted F ig.` 4 is a front view, slightly in section, of a portion ot' the` loom slay, provided with means accordingto the previous figures.' Fig. 5 is a modification of a part of the mechanism, and illustrated on a smaller scaleto `the rest of the figures. Fig. 6 is an end view of the shuttle boX and slay sword, (a portion `of the slay being shown in section),iitted with our improved mechanism; and Fig. 7 is a plan view of `a detail shown in Fig. 6. I

In I "gs. 1, 3, and 4, the reed and parts relating to the samexare shown in the locked position, which is maintained while the shuttleis operating properly; in Fig. G the position indicated is when the shuttle is not` inthe box, in Fig. 2, as above stated,`wh`en the reed is released. y l o. is'the slay, from the top bar 'al of which is suspended the reed b, as is well under-` stood. i The reed is normally held fastiby the bar c: (omitted from Fig. 3), which bar is `at-` taehed to a number of supports, such as c1, iu connection with the special slidable parts, such as d, the whole forming a clamp device according to our invention. i

The parts l are arranged at suitable intervals along the length of the slay, andl each one off which is,in the present example,l as i sumed to consist of `a hollow frame forming side supports, connected together at the one endl by the part c1, and at the other end spanned by a movable block d1. part d is shown mounted ina support or bracket piece attached to and below the slay,` andsuch part beingunelosed above `and bei low, enables aprojection or stud c to pass between the sides oft said piece d. This pro jection e :forms an abutment to the spring h which maybe connected to the support clit desired,`and is shown guided in direction by the pin h1 also connected to said support `01.

The said z The block (Z1 is shown capable oi' adjustment by release ot the same between plate Z2 and set screw di, and by subsequent operation of screws d. i

For the positionshown in Figs. 1 and 3,

the spring It is assumed to be in compression, and is thus tending to force the slidable member d in a direction to release the reed, as indicated in Fig. 2. Under normal conditions this movement of release is prevented by the intervention of a locking piece cl attached to a cross bar 73, which latter is Capable of sliding in a direction at right angles with the movement of the part cl, or thereabout. rlihe piece 701 when operated by the bar la is capable of sliding in and out of a gap or detent between the block all and the slayer bracket thereon, as hereinafter described.

Referring more particularly to Fig. 1i, it will be .seen that the said bar is shown supported by rests, such as 1, attached to a number of br ckets beforementioned, one of which here shown being marked m, such brackets being connected to the slay front at suitable intervals along the length thereof. rlhe extreme portion of said bar ,7e is shown supported by a bracket a, the end of the bar being suitably shaped or provided so as to prevent its `movement for unlocking purposes being excessive.

Referring to Fig. G, o is the external portion of the ordinary shuttle box swell, touching which is a swinging lever p pivoted at p1, and capable on` being moved on said pivot of moving a second lever g pivoted at g1. By this arrangement the movement of the lever g relatively to that of the swell o can be magnified. Also pivoted at Qlis a lever arm r, which is arranged to be moved about its center of turn when the lever Q is moved. This could be accomplished by making the shaft at g1 revoluble and connecting both q and r thereto by an'ordinary shaft key. The said arm r has pivoted to it a nger r1, and when the shuttle enters the box 01 the consequent movement of the swell 0 results in the finger r1 being lifted clear of the shoe or defiector shown at s, and which may` be connected to the loom framing whether adjustable in position or not. Reference to Fig. 7 will show that this shoeis so shaped as to be capable of deflecting the finger r1, when the latter is not lifted clear of said shoe, in a lateral direction, and thus causing the same to impinge against and move the bar k, with the result that the locking pieces, such as k1, are withdrawn from between the blocks (Z1 of the parts ci, and the slay a or brackets m thereon,` thus releasing the reed when the shuttle fails to enter the box or fails to operate the mechanism to lift the finger r1 clear vof the shoe s. The freedom of movement of the finger r1 about its center of turn near the end of the arm r, can be regulated by the degree of tightness of the nuts shown near said end.

A modification of the action of the parts in Fig. 6 is indicated in Fig. 5, in which the shoe .s is replaced by a bell crank lever nii/asse pivoted at s1, and one leg s2 of which extends sul'liciently as to come opposite the end of the bar 7e, `while the other leg s3 is capable of being situated in the path of the lever r1 when the same is not lifted or when the shuttle fails to enter the shuttle boX. r)The leg a2 is assumed to be at a lower level than that of the lever or finger r1, so that on the said finger moving forward for the reason given, the said leg is caused to operate the barv 7u as illustrated. By this means it is not necessary that the finger r1 should be capable of movement in two planes as in` the other example. f

lt is obvious that the actions of the cross bar 7c and locking pieces 701 are not conned to therprecise method or arrangement illustrated, or that if pins on the pieces icl were arranged to enter holes in the blocks (Z1, or vice versa, the effect would be the same. rlhe lower edges of themember or clamp portion CZ are preferably hollowed out as indicated in Figs. 1 and 2, for the purpose of enabling the said member to fall away lfrom the slay when released, as indicated in Fig. 2, almost immediately the locking piece 1? is withdrawn. A spring t is shown in Fig. fl connecting thebracket fn, with the bar L", for the purpose of aiding the locking movement lwhen the member CZ is pushed back into position for becoming locked. For ordinary looms the members such as CZ, together with the remaining clamp parts o1, o, may be pushed back into position after stopping the loom.

l. in a loose reed motion for looms, a clamp for the reed comprisingclamp connections which'are constantly locked while the loom is working properly, but are movable transversely of the lower part of the loom slay, for release of the reed, should the shuttle stop in the shed, in combination with locking'means for retaining the clamp connections in the said locked position, and means for automatically unlocking the same when the shuttlestops as aforesaid, subst-antially as herein set forth.

2. ln a loose reed motion for looms, a clamp for the reed comprising clamp connections which are constantly locked while the loom is working properly, but are movable transversely of the lower part of the loom slay, for release of the reed, should the shuttle stop in 'the shed, in combination with locking members for retaining the clamp connections in said'locked position, laterally and automatically movable means for unlocking said clamp connections when the shuttle stops as aforesaid, and means for so moving said locking members out of action, substantially as herein set forth.

3. ln a loose reed motion for looms, aL

clamp` for the reed comprising clamp connections which are movable transversely of lli! is working tle box, avpivoted finger piece adjacent t0 said connection, movablein two planes, in

the one `plane :for operating said locking member connection, and 1n the other during the normal Working of the loom, and means for moving said nger piece inthe two yplanes aforesaid, substantially as herein set forth.`

4. In a loose reed `motion `for looms, a clamp for the reed com rising hollowed out clamp connections which are movable trans- ;versely of the lower part of the loom slay,

for release of "thereed, locking `members capable of passing between the slay and parts of the clamp connections, a cross bar to which said locking members are attached, and laterally and automatically movable for unlockingsaid clamp connections, a pivoted finger piece adjacent to the end of said cross bar in connection with the swell of a shuttle box, for movement thereby, a pivoted lever uponwhich the said finger piece is livotally mounted for lateral movement, a de shoe connected to a part of the loom, and for so laterally moving said nger piece, when the shuttle fails to enter the shuttle box, substantially as herein set forth.

In testimony whereof we have signed our names to this specification in the presence of two subscribino witnesses.`
